Automatic Power Line Inspection Using UAV Images

Abstract: Power line inspection ensures the safe operation of a power transmission grid. Using unmanned aerial vehicle (UAV) images of power line corridors is an effective way to carry out these vital inspections. In this paper, we propose an automatic inspection method for power lines using UAV images. This method, known as the power line automatic measurement method based on epipolar constraints (PLAMEC), acquires the spatial position of the power lines. Then, the semi patch matching based on epipolar constraints (SPM… Show more

“…While the positioning and self-recovering problems have been addressed, the system was intended for semi-autonomous operations that would require an operator to instruct the UAV. To improve the level of autonomy, images obtained by UAVs can be used to detect inspecting objects and create paths for autonomous flights [22], [3].…”

“…Luo et al [10] proposed an object-aware definition for power lines in joint RGB-NIR images to extract potential segments, followed by intensity features from NIR images to refine outputs. Zhang et al [11,12] applied a hand-designed filter to extract power line features, then adopted epipolar constraints to refine power line segments. Although this kind of approaches have achieved great improvements in recent years, the limitations are still obvious when applied to real environment.…”

“…The status detection of electric power equipment is an essential technique for the high-voltage transmission lines inspection in which a wide variety of sensors are used [1]. Over the past few decades, vision sensor-based methods have been developed rapidly, and many topics have been examined, such as insulator detection [2], power line detection [3,4], and power tower detection [5,6]. Early studies show that the insulator string is one of the most important pieces of equipment of the high-voltage transmission line as it can provide both mechanical support and electrical insulation.…”
